  1. CI confidence interval, CSZ convexity, symmetry, z score, OR odds ratio
  2. aIQWiG’s own calculation: all participants included (211 instead of the 163 actually analysed); both the treatment and control group were of equal size
  3. bIQWiG’s own calculation
  4. cIQWiG’s own calculation, unconditioned exact test (CSZ method as described in [25])
  5. dThe level of significance would not be missed until at least four additional events occurred in the treatment group while no additional events occurred in the control group (assumption)
